Hi All,

We've submitted draft-xiao-v6ops-nd-deployment-guidelines-00.txt.  This draft reviewed known issues and solutions of ND, and proposed some guidelines for future deployments.   Your comments and feedbacks will be appreciated. 

Title:	Isolating Hosts in Layer-2 and Layer-3 to Simplify ND and IPv6 First-Hop Deployments 

   Neighbor Discovery (ND) is an integral part of IPv6 first-hop. Due
   to limitation of certain L2 media's support to ND, a number of
   issues can happen in certain scenarios. The corresponding solutions
   for these issues have also been designed. These issues and solutions
   are summarized in RFC3756, RFC6583, OPSECv27.  However, there is no
   guideline on how to avoid the issues or how to select the proper

   This document analyzes existing solutions and summarizes the wisdoms
   embedded in these solutions into an insight: isolating hosts in L2
   and L3 can be effective in preventing ND issues. In deployment
   scenarios where the ND issues can occur, this prevention approach
   can be more effective than deploying various solutions to solve the
   issues. Based on this insight, a set of guidelines is proposed for
   future ND deployments. These guidelines describe where and when to
   isolate hosts in L2 and L3 to prevent ND issues, and how to select
   suitable solutions for the remaining issues. This will likely
   simplify ND deployments. The impact of the guidelines to other
   components of IPv6 first-hop is also analyzed and appears small.
   Therefore, the guidelines will likely simplify the overall IPv6
   first-hop deployments.
